Allow message callback to set reason code for response #287

Closed embhorn closed 2 years ago

embhorn commented 2 years ago

The application can set a reason code to be sent in the publish response (MQTTv5 only).

Example:

int mqtt_message_cb(MqttClient *client, MqttMessage *msg,
    byte msg_new, byte msg_done)
{
    msg->resp.reason_code = MQTT_REASON_IMPL_SPECIFIC_ERR;
    return 0;
}

This addresses an issue reported by ZD13865.
